To all whom it may concern:

Be it `known that we, 'FRANK C. RICHARD- soN and JOHN T. Woon, citizens of the l United States, residing at Iola, in the county ,5 of Allen, State of Kansas, have invented a l ynew and useful Oil-Burner, of which the yfollowing isa specification.

This invention relates to oil burners particularly designed for use in heaters, coal ranges, gas stoves, and the like so that oil maybe `used as'fuel instead of coal or 'gas such as. commonly employed. l One of the objects of the invention is to t provide a durable and compact structure 1 'i which can be easily placed on the grate of a heater or cook stove and which includes novel means wherebythe Vaporized oil will be thoroughly mixed with the air supplied to the burner in order that practically complete combustion may be obtained.

A further object is to ,provide im roved Y means whereby .the interior ofthe urner can be easily reached for the purpose of cleansing or repairing the same.

view which lwill appear as the description proceeds, the invention resides in the combination and arrangementv of parts and in the details of construction hereinafter described and claimed, it. being understood ",that changes in the precise embodiment of Ele invention herein disclosed can be made ithin the scope of what is claimed, without departing from the spirit of the invention. In the accompanying drawings the preferred forms of the invention have been lshown.

In said drawings t-Figure 1 isl a vertical ransversev section through one vform of mrner embodying the resent improvenents. Fig. 2 is a plan view thereof. Fig. is a plan View of the'base of the burner, he burner rings being removed. Fig. 4 is r plan view of another form of burner parcularly designed for use in coal ranges, a ortion of the central battle being removed. `ig. 5 is a perspective View of the battle' or ixing element. Fig. 6 is an end elevation lereof. Fig. 7v4 is a view partly in section another form of burner, said burner being town in perspective. lReferring to the figures by characters of Iference 1l designates a hollow base suprting spaced circular troughs 2 and 3 .lich are concentric with an upstanding air `fzzle 4 upon the middle portion of the l/Vith the foregoing and other objects in' base. The base is preferably formed of two sections each of which is substantially semicircular, said sections being provided with outstanding lugs secured together by bolts or the like while formed in the sections between the troughs 2 and 3 are webs 6 likewise bolted or otherwise secured together. It is 'to be understood that the troughs eX tend continuously so that oil is free to circulate therein and that` anair space 7 is formed between the two troughs, the webs 6 intersecting this space. Additional reinforcing webs 8 may also be arranged in said space `so as to reinforce the base structure.

An oil distributing pipe 9 is mounted in the base and under the meeting edges of the base sections, said pipe having nozzles 10 projecting into openings formed by registering notches 11 in the meeting edges of the base sections, two of these openin s being provided within each trough at iametrically opposed points, as clearly shown in Fig. 3. A supply pipe 12 extends from the distributing pipe 9 and is adapted to receive oilfrom 'a casing 13 to which oil is fed from a pipe 14 or the like. lA valve 15 is employed for controlling the flow of oil through the pipe 12. An air inlet ipe 16 opens into the base 1 and the pipe 12 1s preferably extended longitudinally through this air pipe, there being an air-inlet opening 17 located at any desired point in the pipe 16 so that air is free to enter the base 1.

Each of the troughs 2 and 3 is adapted to receive a burner ring 18 made up of opposed upwardly converging concentric plates forming a reduced outlet slot 19 which is concentric with the nozzle 4, there being openings 20 within each of these 4plates and close to the slot so that fuel is free to escape not only through the slot but also through the openings in the side plates of the ring. Each ring 18 is fitted snugly within the trough and has oppositely disposed annular offset portions or shoulders 21.

Concentric cylindrical casings 22 are supported by the shoulders 21 on th'e two rlngs 18, each of these casings being. formed preferably of t-wo semi-circular sections hingedl-y connected, as at 23 so that they can be opened out to give access to the interiors of the casings. These casings 2 2 cooperate to form two concentric mixing chambers 24e and 25 separated by an a1r chamber 26, the burner rings 18 being UNITED STATES Patrinir,lcanton. y

adapted to discharge into the lower ends of the chambers 24 "and 25' while the space 7 opens into the bottom ofthe chamber 26. All of the casings 22 are formed with small apertures so that gases are free to circulate from one chamber to another. The cent-ral space surroundedby the inner casing 22 has a mixing element mounted therev in, said element being made up of opposed conical members 27 meeting at their apexes, there being a baffle disk 28 disposed around the .meeting portions of the two conical members. Both of the conical members-as Well as the batie disk are formed with small apertures. lThe upper conical member has an apertured top plate 29 fitting snugly within the inner casing 22 while the lower unconsumed combustible particles will thus y beignitedand as the temperature of the burner is raised the fuel will be completely vaporized within the troughs 2 and 3, the vapor j issuing from slots 19 and commingling with air supplied to compartments 24 and 25 whereupon the combustible mixture will be ignited and produce an extensive flame extending throughout the exterior surface of the outer casing 22, the walls of the compartment 26, and the top of the mixing element 27. Obviously the casings 22 can .be easily shifted off of the base 1 and opened outwardly upon their hinges 23 so that the interiors of the casings can be easily cleaned and access be had lconveniently to the interiors of the troughs 2 and 3.

It is to be understood that the burner may 4be made of any other contours desired in order to fit properly Within fire boxes of different shapes and sizes. In Fig. 4 a substantially oblong burner has been shown for use in the lire pot of a coal range. This bur-ner is made up 'of a base 31 into -which the feed pipe 32 extends, there being a ltransversely disposed distributing pipe 33 arranged within the base and adapted to discharge fuel into the compartments between casings 34 upstanding from the base. These casings coperate to form spaced mixing chambers 35 which are substantially ellipticaland which receive fuel from rings 36 mounted on the base 31. These rings have been shown in plan in Fig. 4 and in cross sectional contour they conform with the showing in Fig. 1. The space surrounded by the inner casing 34 is adapted to be occupied by a mixing element shown in detail in Figs. 5 and 6 and which is of the same cross sectional ,contour as the element shown in Fig. 1, but is elongated so as to extend throughout the length of the base. This element consists'of upper and lower Oppositely disposed members 37 the sides of which diverge from the' center of the element, the upper 'member being closed by an apertured `plate 38 constituting the top thereof while an elongated battle plate 39 extends around the meeting portions. of the upper and lower members. The operation of this burner'is the same as that described in'connection with the burner disclosed in Figs. 1, 2 and 3. l

Another form of burner has been illustrated in Fig. 7, this device consisting of an elongated trough-like base 4'0 having a fuel supply pipe 4l arranged therein. Apertured casing walls 42 extend upwardly from the walls 'of the base 1 and merge into an apertured top 43 from which extend'downwardly inclined aprons 43'.; Oppositely disposed plates 44 'converge upwardly from the lower edges of the walls 42 so as to form a fuel outlet slot 45 extending longitudinally of the burner. Fuel discharged into the trough 40 from the pipe 41 is adapted tov pass upwardly through the slot 45 and to mix with air admitted to the casing through the openings in the walls 42, said air entering the openings from the space formed under the aprons 43. This type of burner .y

is particularly designed for use in gas stoves in lieu of the ordinary gas burners.
